So the top of my roof has these a little vent tile? not sure if thats the right word, but you can see in attached pic of neighbors house (couldn't find good image of mine on streetview)
so right at the top of my roof there is the 'bump' which is a vent.
inside my loft is a metal tube attached to it but this has been stuffed with insulation wadding.
i assume previous owner did this for added insulation but i am wondering if this is necessary. we have a lot of insulation in the loft and have noticed that now its cold we have condensation in the loft.
can i remove 'stuffing' from the tube/chimney to improve ventilation or should this be there?
